RICHMOND, Va. — In the longest and hottest practice of training camp, the Patriots worked in pads against the Redskins for two hours, 45 minutes before cooling down.

Both teams worked up-tempo offensive drills.

Rob Gronkowski was again absent from the practice. Running back Brandon Bolden, receiver Aaron Dobson and center Bryan Stork were again absent. Matthew Slater took part in receiving drills, including red zone chances. Each offense had approximately 90 reps on the day. Alfonzo Dennard took part in individual drills but later joined Deontae Skinner and James Morris on the back field for conditioning work.

Here are some quick takeaways:

Tom Brady and Julian Edelman have looked good all summer working together but Tuesday may have been their best day yet, connecting on a variety of seam routes and sideline patters as the offense worked specifically on hurry-up and no-huddle execution. Danny Amendola also looked good, including early on when, after a Brady incompletion, Brady found Amendola twice, Shane Vereen once and Kenbrell Thompkins. The series ended with Brady connecting with a wide open Amendola down the left sideline for a touchdown.

Later, Brady fired a timing pass on an in cut to Edelman who made the catch and was popped slightly by Keenan Robinson. Edelman’s response was to get up and yell ‘Whooooo’ in Robinson’s ear hole. Brady and Edelman continue to show chemistry as Brady released the ball before Edelman made his cut. Edelman later caught a touchdown pass from Brady in 11-on-11 drills.

On defense, Vince Wilfork and Darrelle Revis provided the highlights. Early on, Wilfork intercepted a pass from Robert Griffin III, much to the surprise and delight of the several thousand Patriots fans in attendance. For the record, it was the second straight day of over 21,000 attendance at Bon Secours training complex. Later, Griffin attempted to connect with DeSean Jackson but Revis was all over the receiver in coverage and batted the pass away cleanly, though Griffin said later he thought there might have been interference on Revis on the play.

Wilfork participated in the early and later 11-on-11 drills while Zach Moore filled in for him during up-tempo and hurry-up situations. Another good sign that Wilfork is ready to go this season and recovered from his Achilles injury came when he rushed upfield later in practice and slipped to the ground. He immediately got up and ran to the sideline as part of a scheduled substitution and return several plays later as part of his regular rotation.

Despite the intense heat and humidity, there were no significant dustups or scuffles on the long day.

Patriots defensive lineman Sealver Siliga left early on with an apparent left hand injury. He returned to the field without his shoulder pads in the final 15 minutes.

The two teams will likely take it down a notch on Wednesday morning, with a walkthrough taking the place of a full scrimmage. The two teams will open the preseason Thursday in Landover, Md. at FedEx Field.
